Method for controlling soybean rust

Abstract

A method for controlling asian soybean rust comprising (α) applying a pesticidal composition (A) to a glyphosate tolerant soybean plant propagation material, and (β) applying a pesticidal composition (B) to the resulting soybean plant, part of plant and/or the locus thereof one or more times: i) before emergence, ii) after emergence, or iii) both (i) and (ii), provided that composition (A) comprises one or more of flutriafol, triticonazole, tebuconazole, ipconazole, epoxyconazole, orysastrobin, prothioconazole fluoxastrobin, azoxystrobin, furametpyr, cyproconazole, a compound of formula (I) and a compound of formula (B), and pesticide composition (B) comprises glyphosate; wherein compound (I) is represented by or a tautomer of such a compound, and compound (B) is represented by formula or a tautomer of such a compound.

The invention claimed is: 
     
       1. A method for improving the yield of a soybean plant comprising:
 (α) applying a pesticidal composition (A) comprising a compound of formula (I) 
 
       
         
           
           
               
               
           
         
         or a tautomer of such a compound, 
         to a glyphosate tolerant soybean plant propagation material, and 
         (β) applying a pesticidal composition (B) comprising glyphosate to the resulting soybean plant, part of plant and/or the locus thereof one or more times (i) before emergence, (ii) after emergence, or (iii) both (i) and (ii). 
       
     
     
       2. The method according to  claim 1 , wherein the propagation material is a seed. 
     
     
       3. The method according to  claim 1 , wherein the composition (B) is applied after emergence. 
     
     
       4. The method according to  claim 1 , wherein the glyphosate tolerant soybean plant is a MON89788 soybean.
